ERNEST O. CARTWRIGHT, OF SPRINGFIELD, OHIO, ASSIGNOB, BY MESNE ASSIGN- MENTS, TO JAMES MCGUNNEGLE, OF NEVJ' YORK, N. Y.

PRINTING-PRESS.

Qriginal application filed August 17, 1909, Serial 1E0. 513.252.

To all whom it may concern:

Be it known that I, Ennns'r O. CART wnioirr, a citizen of the United States, residing at Springfield, in the county of Clark and State of Ohio, have invented certain new and useful improvements in Printing- Presses, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to printing presses, and more particularly to bed and platen presses, and is a division of an application filed by me August 17, 1909, Serial No. 513,252.

The object of the present invention is to provide an improved inking mechanism for bed and platen presses which will distribute the ink uniformly over the form carried by the bed: which will transfer the ink from the ink fountain to the inking drum in such a manner as to convey uniform quantities of ink and to spread the same over a considerable portion of surface of the inking drum.

To this end it is a further object of the invention to provide a vibratory inking drum and a revoluble ductor roller adapted to take the ink from the fountain and deposit the same on the surface of said drum.

It is also an object of the invention to provide an ink fountain having an adjust- .ible feed to regulate the amount of ink removed by the ducttu: roller and of such a. ronstruction as to pre 'ent the flooding of .he ductor roller, and, consequently, of the form should the adjustable mechanism be uridentally loosened.

lVith these objects in view my invention .zonsists in certain novel features and in :ertain combinations and arrangements of arts hereinafter to be described, and then .11016 particularly pointed out in the claims.

In the accompanying drawings, Figure l an elevation of one side of the machine; Fig. 2 is an elevation of the side of the nachine opposite that shown in Fig. 1; Fig. 3 is a longitudinal, sectional view, taken lust inside the side member of the main frame on that side of the machine shown in Fig. 1; Fig. 1 is a vertical, sectional view, 'aken transversely of the machine on the ine of Fig. 1; Fig. is a transverse, .ertical sec-tiontaken on the line y3 of Fig. 3; Fig. 6 is longitudinal, horizontal Specification of Letters Patent.

In these drawings 1 have illustrated one embodiment of my invention and have shown the same as applied to a bed and platen press comprising a. substantially horizontal main frame consisting of the side members 1 connected one to the other by the end members 2. This frame may be supported at a suitable height by means of standards or legs 3. Mounted at the for ward end of the main frame is a normally stationary platen 1, which is capable of movei'nent. as hereinafter described. Each of the side members 1 of the main frame is formed with an elongated opening 5, in each of which is mounted a slide block 6. Each opening preferably provided at its upper and lower edges with adjustable gibs 7 which form the slideways for the slide blocks 6. Mounted within the main frame and carried by the slide blocks 6 is a combined fornrbed and inking drum, which, in the present construction, consists of aframe or carriage 8 which carries both the formbed and the inking drum. This frame 8 is provided at each end with trunnions 9 which extend through the slide blocks 6 and are rigidly secured thereto in such a manner as to prevent any movement of the frame or carriage 8 relatively tosaid slide blocks. A shaft 10 extends longitudinally of the frame 8. through the trunnions 9 and projects a short distance beyond the trunnions at each side of the main frame. The shaft 10 has connected thereto on each side of the main frame a pitman 11, each of said pitmen being connected at its opposite end to a wrist pin 12 carried by a gear 13. The gears 13 are mounted on the outer ends of a shaft 1-1 which is journaled in bearings 15 mounted in the side members 1 of the main frame and projects a short distance beyond the outer sides of said main frame to receive said gears. A second shaft 16 is mounted in bearings 17 arranged in the side members 1 of-the main frame and provided with pinions 18 which are'rigidly secured-thereto and which mesh with the gears 13. The shaft 16 extends some distance beyond the pinion 18'- at one side of the main frame and hasm'ounte-d thereon a drive wheel 19 which is connectedto any suitable source of power.- In the'present instance I have shown the drive'wheel as a belt wheel which is driven by means of the-belt 20 from amotor 21- which is mounted on the main frame.

The form-bed may be secured to the frame 8 in anysuitable manner, but, in the present instance, I have formed the carriage or frame 8 and theform-bed in a single piece, this being accomplished by providing the frame or carriage Swith a flat front face, as shown at'22,=which is arranged parallel with the platen.

The ink'ing drum is formed separately from the carriage or frame 8 and is so mounted thereon asto be capable of a vibratoryorreciprocating movement transversely to the direction of the reciprocatory movementofthe frame 8. The inking drum ordistributing plate may be of any suitable construction and a. vibratory movement may beinip'arted thereto in any suitable manner, but I find the construction herein shown a very satisfactory one. In this construction'the inking drum, which is shown at 23, is substantially semicircular in cross section and is provided at its edges with inwardly extending flanges or guides 24 which are slidably mounted in guideways 25 formed in the upper and lower faces, respectively, of the carriage or frame 8. The inking drum is somewhat shorter than is the frame or carriage-8 and is, therefore, capable of a sliding movement relatively to that frame or carriage. This vibratory or reciprocating movement may be secured in any suitable manner, but I prefer to secure this movement-from the reciprocation of the combined form bed and inking drum. To

this end I have provided one end of the frame S-"and the slide block 6, which sup ports that 'end' of the frame, with alined openings in which isslida bly mounted an actuating bar'26having its inner 'endrigidly secured to an arm or bracket 27, which, in

turn, is rigidl se'eured'to the vibratory inking drum; T e opposite end of the actuating bar 26 extends beyond the slide block 6 and has rigidly secured thereto a collar 28 having a depending projection 29 on which is mounted a roller 30. The roller 30 fits within a cam slot 31 formed in the upper portion of a block or plate 32, which is rigidly secured to the main frame, preferably by casting the same integral with the H lower gib 7. curve and as the frame 8 reciprocates within the main frame, the pro ection 29 traveling in the cam slot 31 will impart two complete vibrations to the vibratory drum for each movement ofthe frame 8. Obviously, however, the construction and arrangem'eiit'of this operating means may be varied and the This cam slot has a double 2 number of vibrations, which are imparted to the inking drum during each reciprocation of the frame 8, maybe varied to meet existing conditions.

The arrangement oft-he inking rollers and the manner of actuating the same is substant-ially the same as that shown and described in the patent granted tome July 6, 1909,

No. 926,851, and consists of a plurality of rollers so mounted as to revolve about the inking drum and across the face oft-he form carried by the forin bed.' To this end the" frame or-carriage 8 is of a length slightly less than the" distance between the 'inner sides of'the two slide blocks (3 and is provided between'each end thereof and theadjacentslideblock with a trunnion or aninif lar bearingsurface'33, which is preferably" formed integral with the frame. Rotatably mounted'on the 1311111111011 or'be'aring surface 33 is a plate-34 having a bearing 35which extends about the'trunnion 33 and which has rigidly secured thereto, near the outer edge thereof, a sprocket wheel .36, There is a plate 34- at each end of the frame or car riage S'and each plate has a plurality of slots orguideways 37'which are arrangedsubstantiallyradially and in each of 'whiclr is mounted an elongated slide block 39 having-grooves'in its opposite sides to engage the side opposite the inking roller. A coiled The opposite or outer end of each slide block 39 has a projection.

"or pin 43 extending laterally therefrom on spring 45 has one end connected to the pin or projection 43 and its opposite end con nected to a pin or projection 38 carried by the plate 34. The arrangement of the spring 45fis such thatit tends to moveth'e slide block and, consequently, the end of the roller shaft 41, which is mounted there in, inward1y;'i. 6., toward the inking drum and form bed." It will beappa-reiitfthere iso fore, that as the plates 34 revolve and carry the inking rollers about the combined formbed and inking drum, the rollers will accommodate themselves to the surface of the form-bed or drum and will receive the ink from the inking drum and distribute the same evenly over the form-bed. The inward movement of the inking rollers is limited and controlled by rollers or casters 46 which are mounted upon each end of the shaft 41 of each inking roller 42 and which travel upon suit-able tracks extending about the frame or carriage. These tracks are preferably formed by annular members or plates 47 which are secured to the ends of the frame or carriage 8 and have their edges arranged substantially parallel with the inking drum and form-bed and spaced such a distance therefrom as to support the inking rollers in proper engagement with the inking drum and form-bed. Movement is imparted to the plates 34, which carry the inking rollers, by means of sprocket chains 48 extending about the sprockets 36 which are secured to the bearings of said plates and about other sprockets 49 which are ec- {eentrically mounted on the shaft 14 which carries the driving gears 13. The eccenitricity of the sprockets 49 is such as to mainltain the sprocket chains 48 at a proper tenision at all times'during the reciprocation of the frame 8. If desired, the plates 34 may be connected by transverse rods 49 to --maintain the same in fixed relation one to the other.

I A suitable ink fountain is mounted in the rear portion of the main frame and preferably consists of two end members or plates 50 which are mounted upon a rod 51 which extends through the lower portions of the end plates and is supported at its opposite ends in the side members 1 of the main frame. The forward portions of the plates 50 are supported on a shaft 52 which is journaled in bearings 53 formed in the side members 1 of the main frame. Mounted betweenvthe end members or plates 50 is a frame comprising vertical members 54 and 55. Supported above the frame comprising the members 54 and 55 is a forwardly inclined plate 56 which forms the bottom of the ink receptacle and has its lower edge bearing normally against a. feed roller 57 which is carried by the shaft 52. In order to maintain the plate normally in engagement with this roller the plate is formed of resilient material and is so arranged that the lower edge thereof, when free, willmove into engagement with the roller and thereby cut off the supply of ink. Means are provided for moving the lower edge of the plate 56 away from the roller 57 a distance sufiicient to feed the desired amount of ink, and, to this end, the forward edge of the plate 56 is provided with a depending flange 58 having a series of openings therein adapted to receive the forward ends of a series of rods 59 which extend through openings near the upper edges of the upright plate 54 and through slots 60 in the upright plate 55, the rear end of each of the rods or bolts 59 being provided on the inside of the plate 55 with a' fixed washer 61 and on the outside of said plate 55 with a thumb screw 62. Thus, it will be seen that the rods 59 fulcrum on the plate 54 and that the adjustment of the rear ends of said rods in the slots 60 will cause the forward ends of the rods to move the lower edge of the plate 56, forming the bottom of the fountain or ink receptacle, toward or away from the roller 57, thereby not only enabling the amount of ink fed to the forms to be regulated, but also enabling different amounts of ink to be fed to different portions of the forms. It will also be observed that should the thumb screws, or other fastening means, for the rods 59 become loosened by the jar of the machine, the lower edge of the plate 56 will move into engagement with the feed roller 57 and thus automatically cut off the flow of ink and prevent the flooding of the forms.

The feeding of the ink from the fountain is controlled by the rotation of the roller 57 and. means are provided for interrupting the rotation of this roller without stopping the machine, and, to this end, I have mounted in one of the side members 1 of the main frame a screw-threaded plug 63 which is provided on its outer endwith a milled nut 64 and has its inner end extending beyond the inner side of the frame member and provided with a bearing lug or trunnion 65 adapted to enter a recess 66 formed in the adjacent end of the shaft 52. l n the opposite frame member 1 of the main frame there is journaled a short shaft 67 which extends beyond the opposite sides of the frame member, is provided on its inner end with an enlarged head to hold the same against longitudinal movement and is detachably connected to the shaft 52 of the feed roller 57. The outer end of the short shaft 67 has rigidly secured thereto a disk or plate 68 in which is slidably mounted a pin 69. A sprocket wheel 70 is rotatably mounted on the shaft 67 between the disk 68 and the main frame. This sprocket wheel has rigidly secured thereto a pin 71. The pin 69 is slidably mounted in the plate 68 and when its inner end is moved beyond that plate it will lie in the path of the pin 71 carried by the rotatably mounted sprocket 70. This sprocket is actuated by the sprocket chain which actuates the duetor roller and rotates continuously. Therefore, the rotation of the feed roller may be controlled by moving the pin 69 into and out of the path of the pin 71 carried by the sprocket wheel 70. Suitable means are provided for so actuating the pin 65). This means, in the present instance, consists of a lever 72 having one end pivotally connected to the plate 6Snear the outer edge thereof, as shown at 73, and its inner end located substantially centrally of the shaft 52 of the feed roller and provided with a suitable handle 74:. The lever 72 has formed therein, betweenits opposite ends, a slot 75 adapted to receive a pin or projection 76 secured to the outer end of the pin 69, whereby the movement of the lever 72 about its pivotal center will move the pin 69 into or out of the path of the pin 71. The pin 69 is preferably provided with two or more notches 7 adapted to be engaged by a pawl 78, carried by the plate ('38, to hold the pin in its adjusted position until the lever 72 has been actuate-d. Thus, it' will be observed that the means for connecting and disconnecting the feed roller from the driving mechanism can be readily operated from the outside of the machine and that, by arranging the handle in the axis of rotation of the shaft carrying the'feed roller, this handle will remain substantially stationary, and inasmuch as the outer'portion of the lever carrying the handle lies close to the plateGS, this operating mechanism presents but a small amount of projecting surface which might be dangerous to the operator when the machine i's'being driven at a high rate of speed.

A suitable ductor roller is provided for transferring the Link from the fountain 'to the inking drum, and, in order to secure the most satisfactory results, I prefer to employ a revolving ductor roller. To this end a' shaft 80 is'journal'ed in the side memhers I of the main frame at a point. substantially midway between the feed roller 57 of the fountain and the inking drum 23. Rigidly secured to the shaft 80 are two arms 81 which carry a ductor roller 82, which is rotatably supported at the outer ends thereof. It is desirable that the support for the ductor roller should be resilient in order that a yielding pressure may be exerted upon the feed roller and the inking drum and also that it should be adjustable to permit the adjustment of the ductor roller relatively to its cooperating parts. To this end each of the supporting arms 81 is provided at its forward end with a bearing 83 and has arranged between the be'aring 83 and the shaft 80 a laterally extending web 84 which terminates short of the bearing 83. A lever 85 is pivotally mounted on the bearing 83 and has a depending portion 86 in which is journaled the adjacent end of the shaft 87 of the ductor roller 82. The body portion of the lever 85 extends above and substantially parallel .with the web 84; of the arm 81 and is movable toward and away from the same as the lever moves about its'pivotal connection to the forward end of the arm 81, thereby moving the ductor roller 82 toward or away from the shaft 80. A bolt 88 extends loosely through that end of the lever 85 lying adjacent to the shaft 80 and also extends loosely through the web 84 of the arm 81 and for some distance beyond the same. A spring 89 is coiled about that portion of the bolt 88 which lies beyond the web 8i and is confined between the web and a nut 90 screw-threaded on the end of the bolt. The tension of this spring tends normally to draw the end of the lever 85 toward the web 84; and thereby move the ductor roller 82 away from the shaft. This inward movement of the lever 85 is limited, however, by means of a set screw 91 which is screw-threaded into the web 84: and is locked in position therein by means of a jam nut 92. By means of the resilient support for the roller 82 a longer wipe or contact is secured with both the feed roller 57 and the inking drum, thus spreading the ink over a larger portion of the ductor roller as it receives the same from the'feed roller and then spreading the same over a still larger surface of the inking drums, and, by means of the set screw 91, the amount of pressure exerted upon the roller, and consequently, the length of the contact, may be adjusted. The resilient sup-port for the ductor roller 82 also serves to absorb the shock incident to the contact between the ductor roller and its cooperating parts when the machine is being operated at a high rate of speed, It will also be observed that by employingfa rotary feed roller in connection with the revolving ductor roller the period of contact of the ductor roller andfeeding roller is materially lengthenedjarid the friction between these parts eliminated, thereby producing an easily operated device having a high degree of efficiency.

Movement may be imparted to the shafts 52 and 80 in any suitable manner, but I prefer to provide each of these shafts at one end with a sprocket wheel, 70 and 94, respectively, about which extends a'sprocket chain 95 which also extends about a sprocket wheel 96 mounted on the shaft let between' the machine and the opposite or outer side of the machine is kept comparatively free from moving parts.

In the operation of the machine it will be apparent that the ink is carried from the fountain on the surface of the feed roller 57 that this roller is engaged by the ductor roller 8:2 which removes a portion of the ink from the face of the feed roller and transfers the same to the surface of the inking drum; that, as the inking rollers pass over the inking drum, they remove a portion of the ink therefrom and distribute the same over the face of the form carried by the form-bed; and that the vibratory move ment of the inking drum, while the inking rollers are in contact therewith, serves to distribute the ink evenly over the length and circumference of the inking rollers and thereby cause the same to be applied evenly to the form.

As above stated, the normally stationary platen at is mounted on the forward portion of the machine with its working face arranged at substantially right angles to the line of movement of the combined form-bed .and inking drum. This platen is designed for use with a machine operating either as a hand fed press or an automatically fed press, and, to this end, the platen at is loosely mounted on a shaft 193 supported in the opposite side members 1 of the main frame and is provided with means for automatically moving the same about its pivotal center on said shaft, when it is desired to use the press as a hand fed press. To this end 1 mount on one side of the platen a guide 19% and mount a similar guide 195 on the corresponding side of the frame at a point near and preferably beneath the guide 191. An arm 196 is detachably secured to the slide block 6 adjacent to the guides 19% and 195, this arm being attached, in the present instance, by means of a removable bolt 19? which forms a pivotal support for the adjacent end of the arm. The arm 196 extends between the guides 19% and 195 and has its upper and lower edges diverging toward that end of the arm opposite the point of connection to the slide block. Thus, it will be apparent that when the arm 196 is connected to the slide block and the slide block moved away from the platen, the di verging edges of the arm 196 will force the guides nu and 195 apart, and, inasmuch as the guide 195 is fixed to the main frame, the guide 191 and the platen, to which it is secured, will be moved upwardly and the platen raised to a position in which the paper can be readily fed thereto. As the guide blocks move toward the platen the diverging or wedge-shaped end of the arm 196 is moved from between the guides and the platen permitted to resume its normal position. Suitable adjustable stops 98 are provided to limit the downward movement of the platen and to maintain the same in true parallelism with the form-bed. l/Vhen it is desired to operate the press as an automatically fed press the arms 196 are de tached from the slide blocks 6 and the paper carried from a roll 99, supported beneath the main frame, over the face of the platen and through the automatic fee-ding mechanism 100 which is supported upon a frame 101 movably mounted upon the forward portion of the main frame and adapted to be moved toward the rear of the press when it. is desired to operate the press as a hand fed press. This automatic feeding mechanism forms no part of the present invention and is, therefore, not shown or described in detail. The driving mechanism for the automatic feed is here shown as a sprocket chain 102 extending'about a sprocket 103 mounted on the outer end of the shaft 80. In order that. the operation of the feed mechanism may be stopped and started as desired a suitable clutch mechanism is provided, and, to this end, the sprocket wheel 103 is loosely mounted upon a bearing block 104 which is rigidly secured to the outer end of the shaft 80 and has slidably mounted therein a pin 105. The end of the shaft is also provided with a longitudinal socket or recess 106, in which is slidably mounted a rod 107 having at its outer end a handle 108. This rod is provided near its inner end with a recess 109. 1Vhen the rod 107 is in its innermost position the pin 105 will be in its outermost position and will engage a notch 110 in the sprocket wheel 103. lVhen the rod 107 is moved to its outermost position the pin 105 will drop into the recess 109 and the outer end of said pin will be moved out of the notch 110, thereby leaving the bearing 10% free to rotate independently of the sprocket 103.

The operation of the press will be readily understood from the foregoing description and it will be apparent. that in the course of this operation the ink is fed from the ink fountain by the feed roller, the fountain having been adjustedto regulate the amount of ink so fed; that the revolving ductor roller will engage the feed roller, and, owing to the rotation of the two rollers and the resilient support for the ductor roller, the two rollers will remain in contact a considerable length of time and the ink taken by the duetor roller from the feed roller will be dis tributed over a considerable portion of the surface of the ductor roller; and also that, owing to the resilient support for the ductor roller, the contact between the ductor roller and the feed roller will be a gentle one and there will be no jar or severe impact between the two parts and the noise and shock ordinarily incident to the operation of the ductor roller will be largely eliminated. As the ductor roller revolves about its axis it is brought into engagement with the vibratory inking drum and here again the resilient support and the rotation of the ductor roller cause the same to remain in engagement with the curved surface of the inking drum for a considerable length of time and thus distribute the ink over a considerable portion of the surface of the drum. The inking rollers then pass about the vibratory inking drum and transfer the ink therefrom to the face of the form. Owing to the'manner in which the ink has been l'GCElX'QCl by the ductor roller and deposited by the ductor roller on the inking drum, together with the vibration of the inking drum, the ink is very evenly distributed over the inking rollers, and, consequently, is applied uniformly and in equal quantities to the face of the form. Further, the ink fountain being adjustable and having a positively rotated feed roller feeds the ink to the ductor roller in uniform quantities, and, consequently, the same is applied to the forms in uniform quantities, 'it

being apparent that the constant rotation of 1 the feed roller will maintain the ink supply always in contact therewith, thus avoiding the necessity of stirring the ink supply at intervals, as is necessary with the ordinary feeding device. Further, the construction of the ink fountain is such that it is normally closed, and, should any of the adjusting members or bolts become loosened in the operation of'the machine, the fountain will close automatically and thus prevent the flooding of the forms; L

While I have, in the present instance, shown and described the invention as applied to a bed and platen press comprising a normally stationary plat-en and a combined form bed' and inking drum adapted to reciprocate in a right line with the face of said platen, it will be obvious that the invention couldbe readily adapted for use in connection with machines of other types or with modifications of thepresent type. There fore, I wish it to be understood that I do not desire to be limited to the details of construction shown and described, for obvious modifications will occur to a person skilled in the art.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent, is
